Hello
  I dont claim to know anything about PC, But I connect a PC to a Mac using ethernet, and as long as you have the means for ethernet (normally an ethernet card - I think quite cheap now, installed in both computers - then it all comes down to speed of transfer you need.) 
 Its a basic network, saying that I would still recommend a HUB to connect to the internet as your main computer needs protection accessing the net, last thing you need is a virus on the slave computer.

 PS don't quote me I only know my system and it works for me. 
 PPS as your location states " lost in space" see you there
